To all 'whom tmc/y concern.'

Be it known that I, HEINRICH DREWELL, engineer, subject of the German Emperor, residing at Pertalozzistrasse 9, Charlottenburg, near Berlin, Germany, have invented new and usei'ul Improvements in Means for Electrically Operating VType-Setting. Machines, of which the 'following is a specification. u

The present invention relates to means for canceling or neutralizing the effect of groups of holes whichv have been unched incor rectly in register bands useV lfor operating type setting and composing machines. i

Type setting machines Aare already known, in which the casting and composing oi types is controlled by a perforated band, which, when the band contains errors, also contains the representationo a stop or canceling ac tion which stops the action of the casting and composing` device until the incorrectly perforated holes on the band have `passed the machine. Hitherto in'these machines it has been possible to omit Whole lines only; even if one character ofthe line was incorrectly perforated, the whole line had to becanceled and the perforation 'of the line had'to be repcated. The present invention, however, provides very simple lmeans for canceling both single characters, and groups of characters oi option-al length. Another advantage of this invention is that the stopv action or the subsequent releasing action occurs immediately when the respective holes come into the machine. Forthls reason only it is possible `to cancel other parts of the perforated matter than whole lines, for example single char- 'acters or words, and to avoid unnecessary loss of time. j

The means hereinaftelr described in accordance vwith the present invention are particularly suitable for employment in matrix or type composing machines 'in which the matrix or type releasing deyices are operated by electromagnets, the latter being controlled by the pe'rOratedbaDd. The ,employment of the invention is not limited however to this kind of machine.'

Toattain an immediateeiect of the can celing and subsequent releasing holes'whenthey come into the type setting machine the operation of the machineis 4sto ped by disconnecting the character contro ingelectromagnets from the lsource of electl'lc power, this disconnection being',brought about by using the ordinary character se ecting means v ina suitable manner. No special s ace is required in the Width ofthe band for t e cani machine of the Mergenthaler type are also represented. d

In the drawings Figure 1 shows anl arrangement by means of which single groups of holes are neutralized or made ineffective; Fig. 2 represents a ortion of a perforated band Withgrcnps of oles which are made ineffcctive; ig. 3 shows an arrangement for canceling the eii'ectl ofa longer row of holes; Fig. 4 is a variation of the arrangement shown in Fig. 3, Whereas Fig. 5 represents a portion ofa register band upon which a onger series of holes is made 'ineective Fig. 6 is a side elevation and Fig. 7 a plan of the mechanism for feeding the register-band, whereas Fig. 8 is a side elevation, partly in section, of the mechanism by which the electromagnets are operated in a linotype ma chine of the Mergenthaler ty e. l rihe connection shown in gig.- 41 substantially agrees with the parts of the connectionwhich are already known' and described a prior patent No. 864,59, which serves for distributing electric currents by means oi a register band in' such a manner that the electromagnet which corresponds to the perforation of theband 'at any time is operated. The arrangement of the connection 1s as fol- ,lowsze-e ist'he source of current, d the contact brush which connects the roller b with the source of current e; al, a2, a3, a4, a, a, are six more contact brushes which lie on the roller b. The register band c is tween the brushes a to a and t e roller b .and it permits some of the brushes a1 to a6 to contact with the roller 'b as soon as two ofV the holes in the band pass between the roller and the coils 2 to 6 of the automatic switches f 2 to Wg, are connected with the brushes a2 to a he armature levers f 3 and of the assed beswitches f2 to f". The electromagnet g which is put in circuit becomes energized and causes the corresponding-matrix or tylpe to be composed. In this arrangement al the groups of holes consist of two holes. Any

of these possible pairs of holes can be used-v for making pairs of holesy ino erative which have been punched falsely. up ose for. example that the group of holes 'i1 Figs. 1 and 2) which effects a simultaneous contact of the brushes a2 and a3 shall act as a correction symbol. For this urpose the arrangement as above .describedP is altered as follows VThe armature levers of the automatic switches f 2 to f", which are in connection one with another through the conductor Z, are not connected directly with the sourcel of current, but by means of two contacts h2 'and h3 which are connected in parallel by the conductor Z1 connected with the source of current; these contacts serve as stops limiting Aso the normal positionorl the armature levers y which belong to the coils 2 and 3 of the first two switches f and which open the circuit as soon as the current flows throughvthe coils. Now as long as one of these contacts h2 or h3 is open the manner in which the arrangementl works is not disturbed; as soon as both contacts are opened simultaneously however,

vthe sup ly 'of current to theelectromagnets' l of current to the magnets g, g continues,

however, just `as lon as the brushes a? and a3 contact with the rol er b through the group of holes il, and ceases a ain when these holes no longer influence t e brushes. cordance with the present invention the arrangement is such that a group of two correctlon holes 'il which belong-to the brushes a2, a3 is punched in the same transverse row of the band with the false ones, that is with the group consisting of the twe holes x1', x5 which are to be made ino erative (Fig. 1). Fig. 2 shows a portion of a and in which two canceling groups fil, i2, have been" subseuently punched. All the four holes at both t 1e laces are made inoperative with respect to t e electromagnets controlling the type in themanner `above described.

' It follows from the manner in which the arrangement in Fig. 1 works vas above de'- scribed that more thantwo contacts, such as h2, h3, which are connected in parallel can cffect the supply of current to the armature two currents.

levers of the automatic switches f2 to j". But all the contacts must be interrupted simultaneously when the correction symbol is in action. The correction group `must thus 'contain a hole for each of the contacts which are connected vin parallel. lf a somewhat long series of holes is to be made inoperative, in accordance with the present invent-ion the correction symbols or holes for interrupting the current must be added to each group ol' holes. As this would be very troublesome. and as it would occupy much time another arrangement is indicated in Fig. 3 in which one definite symbol or hole interrupts the current until another symbol or hole closes it again. In this arrangement the armature levers of the automatic switches f which are connected with cach other by a conductor Z must likewise be separated from the battery e, only not by the armature lever itself, but by a special switch 7c which is under the action of or controlled by two electromagnets p and g.- The switch k is connected with the source of current e by a conductor Z2 and with the armature levers by a conductor l and in its normal position makes contact with u contact s and thereby connects the. levers ot' the automatic switches f with the source ot' current e. The electromagnet g has a coil t in circuit instead of that of the type-electromagnet g, g corresponding to the combination of armature lever and brush 1, 6. As soon as the corresponding roups of holes in the band c are situated un er the brushes 1 to a, the electromagnet g is energized and the lever k is withdrawn from the contact s. The circuit of the. electromagnets g is thereby interrupted. The lever k now lies against the -two contacts r `which connect two coils 1t and m on the electromagnet p to the source olt current e. These coils are connected on the other side with thc brushes c and a5 and receive current as soon as the group of holes r, x5 passes under the appertaining brushes. The lever c is so arranged that it remains in the position which it occupies at any time until it is moved over by one of the electroma nets p or g. ',lhe manner -in which it wor s may be brought about in known manner by the entire switching means including lever r and electromagnets and q with coils` m, n, t being made like a poiiirized relay such as is used in telegraphy l'or operating with Further, the electromagnet p is so proportioned and adjusted that it onl \Y works when both its coils lmand n. have eurrent flowing through `them simultaneously. In this connection therefore, the group or combination of holes w1, acts as circuit breaker and the combination r1, x5 as circuit closer.

In Fig. 5 in which a portion ot a register band is shown in which the combination ol' holes x, x and r1, '.v" are added at z and zi' to the incorrect combinations which are pres llt) the lever c must be moved very quickly sol that it interrupts the current before the electromagnets which control the types are o erated. The rapid movement of the'lever at z2 would however bring'about the disadvantage which is thereby avoided at 21; for when the circuit at the contact s is closed teo early, the electromagnets which control the type are operated simultaneously-.by the roups of holesat z2. This disadvantage can e avoided in various Ways. For example, the holes w1 and x5 which effect the closing of thecircuit may be set back from the remaining ones so much that the cimuitis closed too late in order to allowV the remaining holes of the row'to act, as shown in dotted lines in Fig. .5'. 1 Namely in this igure the holes r1, x on line .el are represented in dotted lines in an advancedl position for the Apurpose of interru ting the current` in time. Another possi le manner of avoiding this defect consists in a group of holes for closing the circuit being employed whichis used' repeatedly on the band for other reasons, for example the sign for the end of the line, whichsign does not contain holes which are'able-to actuate type. In this case it is true only whole lines or those which are begun can beremoved, which however is not disadvantageous because' the removal of single parts of `a line generally leads to difficulties. A double action of the sign which could take effect before 2* and at z2 is then not inconvenient. e

A third method of removing an unintentional effect of the correction sign for` closing a circuit leads to the connection which is indicated in Fig. 4. In this case the employment of the connection in Fig. 1 is combined with that in Fig. -3 bythe coils m, n of the electromagnet pl(Fig. 4) lbei nected in serieswith the coils 2 an 3 of the automatic switches f. Further, the conductor from the contact s is not led directly to the armature levers-belonging to 'the coils 2 and'3 ofthe first two switchesf,

but first to two contacts h2 and ha which are arranged symmetrically and actas in Fig. 1. The coil t ofthe electromagnet q is likewise connected as in Fig. 3,. The manner in ywhich Y this arrangement Works is as follows: The correction symbol for interrupting the current acts just as in the con-V nection according to Fig. 3. The correction symbol for closing the circuit does not now consist of the holes x1, 'x5 however, but of the conholes x2, x3. When these come into action the lever k is returned to the contact s. But the circuit of the electromagnets for operating the types is simultaneouslyl interrupted at h2 and h3 for the entire period 'of the correcttion symbol for closing the circuit and is only'- completely closed when the lever of the automatic switches 2 and 3 return' into their normal position. Thus there is no uncertainty with regard to the point of time when the circuit is closed. The arrangement according to Fig. 4 moreover gives the possibility of making single errors inoperative by the combination of holes m2 x3.

In Figs. 6 and 7 is shown Vthe mechanism for, feeding the register band. -In these figures c is the register band which passes first over the contact roller b and'then bctween the feed-rolls 60 and 61. 0n the axle 62 of the roll 61 is located a ratchet-wheel 63, the teeth of which are engaged by a pawl 64. The pawl 64 is pressed by spring 66 on the teeth of the wheel 63 and is attached to the armature 66 of the electromagnet 67. The electromagnet is located in the manner of an automatic interrupter in the circuit of4 the source of current el. Inthe circuit is a contact-screw 68 against which the armature 66 rests when the electromagnet 67 is not excited'. As soon as the circuit of the source of current is closed the electromagnet -67 attracts its armature 66 and moves the ratchet-wheel 63 by means of the pawl 64;

.The current 4passing simultaneously through the electromagnet 67 is interrupted at the contact-screw68 andthe armature 66 is returned by the action'of the springr 65. This action is repeated as long as the circuit of the electromagnet is not interrupted at some other place and the ratchet-wheel 63 is rotated a tooth at a time. With the same there is moved the small feed-roll 61, 'which' a ain feeds the paper-band c. For each type W ich is to be set the register band has "two holes Le' etc. which are placed simultaneously'under thebrushes aly to a and close fthe corres ending circuits.

Fig. 8 il ustrates the mechanism by which the electromagnets are operated in a linotype mach-ine of the Mergenthaler type. 'lhe mechanism for releasingv the matrices is of. the usual` form, and therefore needs no description.. 'l Under the keys of this apparaown They consist of a coil-g1., core g2 i of employment in other connections which i nations being chosen from the ordinary serve for distributing currents corresponding to the perforation of the band. Consi e ration must however be paid to the 'fact that all theholes of a combination or group which is used for canceling single mistakes must act on switches of the kind described as forming part of the embodiments of the present invention.

Generally speaking the'arrangements hereinbefore described in accordance with the present invention have the advantage that symbols for opening and closing the circuits are in the same transverse row of the band with other symbols and accordingly can be punched subsequently.
